LUBRICATING MECHANISM.

Specification of Letters Patent.

Patented Apr. 1, 1919.

Application filed October 16, 1916. Serial No. 125,914.

To all whom it may concern.

Be it known that I, WILLIAM M. TEMPLE- 'ION, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Lubricating Mecha nism; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to oil pumps. It relates more particularly to a pump used for the lubrication of steam cylinders of engines or pumps and particularly in connection with sight-feed lubricators through which the oil or lubricant is fed in small portions at regular intervals to such cylinders.

The primary object of the invention is to provide an exceedingly simple but efficient form of pumping mechanism havingits intake submerged in a reservoir which is kept supplied with oil as a lubricant to be pumped to the place for use in which a certain quantity of graphite is placed, the said pumping mechanism including an agitator for constantly agitating the oil whereby. the graphite will be kept in suspension, the. oil and graphite thus mixed beingpumped to the place for use. A

My pump is very simple in construction, there being no working parts to become worn and in time require repairing or. re-

found in some of the older types.

To the end that my invention may be understood, I have provided the accompanying drawing, in which, I

Figure 1 is a plan of the device;

Fig. 2 is a sectional elevation of the same on a larger scale with parts shown in section. a

Figs. 3, 4 and 5 are endelevations ofa shaft and eccentric in their different positions in operation.

A indicates a receptacle preferably of cast iron, by which to provide a construction of low cost, the same being provided with a lid B having an opening covered by a plug or other suitable closure B.

C is acasting constituting a part of the pumping mechanism. This may be suitably secured upon the bottom of the receptacle, for instance, or to some other portion so that its intake will at least be submerged Fig. 1, and in this instance may be entirely submerged in the oil and graphite with which the receptacle is kept supplied. It is provided with a bore F disposed longitudinally thereof and extending but part way through the same, the open end of said bore being closed by a suitable plug G as a structural expedient.

Below one end of the bore F is a second shorter bore H lying close to the bottom of the receptacle, by preference, and open at its outer end, the two bores communicating througha passage J controlled by a ball K seated at the upper opening thereof within said boreF. In line with the passage J and the'ball is a bore L extending at right angles to the bore F, said bore L being threaded at its open end to receive a stem M overhanging the ball substantially as shown for purposes to be explained.

Above the other end of the bore F is a bore 0 opening through the end of the casting G, into which is screwed a pipe P lead ing tothe lubricator or other device that supplies the engine or pump cylinders with the lubricant. This said bore 0 communicates with the bore F through a passage Q controlled by a ball R seated thereon. placing such as ratchets, gearing or the like I upward or opening'movement of the ball R closes an opening through the top of. the casting through which the communicating bore Q is created.

' T is a bore extending vertically through the top of the casting and communicating with the bore F. Within this a piston U is designed to work at a snug fit. rAbove the casting C is a shaft V suitably journaled in the walls of the'receptacle provided with an eccentrically disposed portion W. In passing, itmay be stated that for convenience in constructing the shaft, it and the eccentric W are one. That is to say, each end of a shaft the diameter of the said eccentric portion W is turned 01f at its ends in a manner to create the eccentric portion, the axes of the said ends being, of course, coincident. The outer end of the shaft carries any suitable connection at 2 such as an arm, for example,

to be rocked or vibrated by a part of the engine or pump to be supplied with. the lubricant, or by any other desired method. The means for imparting this movement is not shown since it is of secondary consideration.

Placed upon the eccentric portion 1V is an eccentric strap 3 from which depends a rod connection 4 whose lower extremity has pivotal connection with the described piston U through the instrumentality of a pivot pin 5, for example, or other means.

Depending from the shaft V and from the eccentric \V, one at each side of the casting C, is an agitator taking the form,

a in this instance, of a perforated plate or arm 6 preferably disposed so that the plane of each lies at an angle to one another and to the axis of the said shaft.

As has been stated, it is my purpose to provide a pump for positively moving a lubricant to a place for use and mix graphite with the lubricant which, as is well known, is a very valuable addition as a lubricating substance. The tendency of graphite even in a very finely divided form is to sink tov the bottom of any fluid with which it may be mixed, including oil. Because of this fact it becomes necessary to keep the oil in constant agitation in the receptacle A so that the graphite will be held in suspension and evenly mixed throughout the entire bulk.

To this end the depending plates or arms 6 receiving the oscillating or swinging movement thoroughly and constantly mix the oil and graphite. The intake of the pump being immersed in the mixture, the latter is forced to the place or places for use.

As stated, said shaft V may receive its movement from a vibrating portion of the engine or pump or from any other desired source and the oscillatory movement of the shaft, besides imparting the desired sweep to the arms 6, imparts vertical movement to the piston U, each upward movement drawing the lubricant into the bore H and up past the ball K into the bore F, the downward movement of the piston forcing the lubricant up through the bore Q beneath the ball R and out through the pipe P to the lubricator or other place for use. The ball-valves prevent the return flow of the lubricant so that the movement of the latter is always a progressive one and since the graphite is in constant agitation and always in suspension it must, of course, be carried to the final delivery point within the steam cylinder.

The threaded stem M extends through the top of the receptacle A in position to be turned by the attendant. By adjusting it the ball-valve J may be permitted to open as little or as much as desired depending upon the flow of lubricant required.

Any other means, of course, may be adopted for keeping the lubricant in agitation whereby to keep the graphite in suspension since it is not my purpose to be confined to the structure described and shown, this being merely one mode of accomplishing the purpose, and I may make changes in the construction of the pumping mechanism without departing from the spirit of the invention and the meaning of the claims.

The form of the pump is exceedingly simple and can be readily manufactured at small expense and it is absolutely positive in its action. The piston requires no packing, due to the fact that as the pump is submerged the snug working fit being aided by the oil and the small quantity of the latter that may, perhaps, pass the piston is negligible.

It is evident that I can impart more or less throw to the arms 6 and a greater or less movement to the piston U by increasing or decreasing the amount of throw of the eccentric portion W and indeed the shaft V having said eccentric portion may be rotated, if desired, in which event the shaft will, perhaps, occupy a slightly different position within the receptacle so that the agitators in rotating would have unrestricted movement in accomplishing the purpose for which they are designed.

I prefer to suspend the agitators 6 so that they reach substantially to the bottom of the receptacle A, as well as substantially through the entire depth of the lubricant, each of them lying adjacent opposite walls so that in their swing they will most thoroughly agitate the lubricant thereby keeping the entire bulk stirred, mixing the graphite thoroughly throughout.

I am aware that an agitator has been placed in the bottom of a receptacle in a lubricator device torotate in a horizontal plane but such an arrangement does not yield the proper and desired results in practice but by having the agitators disposed as described herein the best results can be realized in the quality of the lubricant pumped to the places for use.

Having thus described my invention, I claim 1. In a device of the class described, in combination, a receptacle for containing a. lubricant, means for discharging the lubricant from the receptacle including a part within the latter spaced from its walls, a rock-shaft, an agitator suspended therefrom at each side of said part and terminating at its lower end in close proximity to the bottom of said receptacle and adapted for stirring the lubricant in the movements of said rock-shaft, said agitators being disposed in planes lying at an angle to one another.

2. In a device of the class described, in combination, a receptacle for containing a lubricant, means for discharging the lubricant from the receptacle including a part within the latter spaced from its Walls, a rock-shaft, an agitator suspended therefrom at each side of said part and terminating at its lower end in close proximity to the bottom of said receptacle and adapted for stirring the lubricant in the movement of said rock-shaft, said agitators being disposed in planes lying at an angle to oneanother, and each rovided with an opening extending through it.

3. In a device of the class described, in combination, a receptacle for containing a lubricant, means for ejecting the lubricant from the receptacle including a part spaced from the walls of the latter whereby the lubricant can have free movement entirely around said part, a rocking portion, an agitator-plate depending therefrom, one at each side of said part, each terminating at its lower end in close proximity to the bottom of said receptacle, the plane of each inclined at an angle to the axis of its movement and both being spaced at their lower ends in opposite directions from a plane lying parallel to the axis of movement of the rocking portion.
